STEREOTYPE-CASTI NG APPARATUS.

SPECIFICATION forming'part of Letters Patent No. 240,8(39, dated May 3,1881.

Application filed January 525, 1881. (No model.)

To all whom it may concern:

Be it known that I, ELIJAH P. BROWN, of Cincinnati, Hamilton county,Ohio, have invented a new and useful Improvement in Stereotype-CastingApparatus, of which the following is a specification.

My invention relates to improvements in those apparatus inwhichstereotype-plates are cast upon a wooden back or block and in contactwith apreviously-prepared paper matrix, my improvements having for theirobject greater accuracy and an important saving of time and labor overthe devices customarily employed for this purpose-that is to say, wherea number of stereotype-plates are to be cast from one matrix.

In the accompanying drawings, Figure 1 is a vertical section, at rightangles to the hinge, of my castingapparatus in the open condition of theflask. Fig. 2 is a similar section in the closed condition of the flask.Fig. 3 is a section on the line to w of Fig. 2. Fig. 4 is a sideelevation, showing the flask in condition to receive the moltentype-metal. Fig.5 is an underside view of the upper member of the flask.Fig. 6 is a side view of the same. Fig. 7 is a section on the line a::r. Fig. 8 is a top view, and Fig. 9 is a section on the line g y. Fig.10 is a side view of the lower member of the flask. Fig. 11 is a sectionon the line z z.

A may represent a suitable cast-iron frame. The said frame has at itsupper portion two notches, B, which constitute the bearings for thetrunnions O of the drag or lower member, D, of my flask, D E. The memberD has slotted ears F, for the reception of pintle Gr upon' the cope orupper member, E, whereby said members are so hinged together as to becapable of being opened and of being again closed without disturbance oftheir proper register, and yet be capable of self-adaptation toward andfrom one another to accommodate different thickness of matrix. The dragD is supported in its horizontal position in front by one or more rests,H, and in rear by a catch, I, which is pivoted to the frame at i, andhas an operating-lever, J. y

Projecting rearwardly and upwardly from the frame are other rests, K,that serve to support the cope is its open position. (See Fig.1.)

L is a rectangular frame, whose inside measurement corresponds with theinner boundary of the margin of customary paper matrix, M. This frameconstitutes, with its springs N, wrists O, and eccentrics P, the matrixclip or fastening.

One portion, 1, of frame L is thinner than the rest of the said frame,in order to provide an entrance-passe ge or gateway for the moltenmetal.

For holding the customary back board or blocking, Q, there projects fromthe under side of the cope E an L-formed curb, R, to which the blockingis retained by means of an eccentric button or clamp, S. The matrix andthe blocking having been thus'secured, the cope is closed down and heldshut by the hand-screw T upon the swivel-bracket U. This having beendone, the catch Iis released by liftingits lever J, and the flasksuffered to swing to the position shown in Fig. 4, which, presenting thegateway L uppermost, enables the molten type-metal to be poured into themold.

Shoulders V or other suitable devices are employed to guide the cope totrue register with the drag.

While selecting, to illustrate my invention,

the preferred forms for carrying the same into effect, said forms may,nevertheless, bevaried in non-essential particulars. For example,screws, wedges, or other well-known tightening devices may be usedinstead of the cams P and S, and in association with a box or flask,whose members are held together by other means than hinges. l

I disclaim invention in the casting-box or flask here shown, as well asin the devices for securin g its members to one another, and forsupporting the flask in its frame, a description of these accessoryparts having been given simply for the purpose of conveying a completeunderstanding of the clamping devices for holding the matrix and theback board in their respective relative positions in thebox.

I further disclaim novelty in the several fastening and clampingdevices, separately considered.

I claim as new and of my invention In the described combination with thetwo parts or members of a flask for casting a stereotype-plate upon itswooden backing, the gated matrix-clip L I, having; the tightening deviceP in one part for holding the matrix 5 immovable, and the curb R andclamps S for holding the Wooden back or blocking in the other part,substantially as set forth.
